AC power contactor LS Electric MC-225a 400VAC 2a2b MC-225A 400VAC 2A2B

LS Electric Power Contactors – Reliability and Efficiency in Automation

The LS Electric MC-225A power contactor is a component designed for frequent switching of electrical circuits, especially in applications related to automation and power distribution. It is a solid solution that will find application both in industrial installations and in more demanding commercial applications. Reliable operation and high-quality workmanship guarantee long-lasting and trouble-free operation.

Construction and operating parameters

This three-pole contactor (3P) with a rated current of 225A is designed to operate at 400VAC. It has a configuration of auxiliary contacts 2a2b (two normally open and two normally closed contacts), which provides flexibility in connecting control circuits. Mounting on a DIN rail or panel facilitates integration with existing infrastructure. A width of 138mm and a height of 203mm allow for efficient use of space in the switchgear cabinet. The contactor operates in a temperature range from -5°C to 60°C, making it suitable for most industrial environments.

Application and benefits

The MC-225A contactor is ideal for controlling electric motors, heaters and other loads requiring frequent switching. Thanks to its high mechanical and electrical strength, it ensures a long service life even with intensive use. Standardized dimensions facilitate the replacement of existing contactors from other manufacturers. It is worth noting the possibility of mounting capacitor modules, which allows for optimization of the operation of inductive circuits. In addition, the availability of a wide range of accessories allows the contactor to be adapted to specific application needs. Withstanding impulse current allows for safe starting of devices with electric motors – characteristic C provides a delayed reaction to short-term current surges.
